Application filed July 30, 1924. Serial No. 729,126.

To all whom it may concern:

Be it known. that I, RENSSELAER H. TOLL, a citizen of the United States, residing at Long Beach, county of Los Angeles, Cali-- fornia, have invented a' new and useful Improvement in a- Self-Starting Cream Remover, of which the following is a specification.

This invention relates to siphoning lapparatus and has for an object toprovide a device of utmost simplicity, and which is self-starting in action.

An object is to provide a siphonic device consisting of a simple tube of practically uniform diameter, and having, in its preferred form but a single liquid inlet.

An object is to rovide a siphoning. device which can rea ily be cleaned and kept sweet and sanitary, which is an important feature when the device is to be used, for removing cream from above milk in the common milk bottles.

Other objects and advantages will be made manifest vin the following specification of apparatus of this invention, embodiments of which are shown in the accompanying drawing; it being understoodv that other modifications, variations and adaptations may be restorted to within the spirit of the invention and its scope as here 0 aimed.

The invention consists of means for accomplishing the desired objects.

I am aware that it has been proposed to construct a self starting siphon device by employing an air bell to discharge air through a small hole into a tube having a liquid intake mouth adjacent the air hole so that as air rises in the submerged tube flow will-be initiated at the mouth and continue a difier'ent principle of operation into the to through the tube. An object of my present .invention is to eliminate both the bell and the restricted air port and to provide a more reliably acting device. 7

The present inventlon employs a wholly rom that of dischargin air through a restricted orifice various purposes a great The device here shown comprises a simple tube having a trunk portion 2 to be submerged sufliciently to cover a good-sized inlet rnouth 3;, above which is a goose-neck 4 having a discharge spout 5.

The bottom end of the tube trunk 2 could,

I provide an openbottom end which may be closedby any plug 6 when thetrunk is.

to be submerged.

The devlce 1n its entirety therefore con- "sists of 'a goose-neck tube with an inflow orifice 3 in the trunk, this being closed at J the bottom. The trunk, it will be seen,

forms an air pocket below the liquid mouth 3, which is in full, open, unrestricted and straight communication with the bow of the neck., By repeated use of this device I have found that when the air trunk is submerged in upright position, (Fig. 1) the liquid, rushing downinto the trunk, displaces the air which, of its own 'property, tends to rise and expand in'reaction to the pressure of the incoming liquid. As the air rushes up'past the inflow mouth 3 and into the neck A, a.

positive upflow of liquid is "established in the neck and spout, and this flow continues until the level of the liquid in the container (here shown as a milk bottle) A, falls to the mouth 3.

While the apparatus may be employed for field of use is to remove cream from milk in bottles. In this use it is important to keep the device perfectly clean and I therefore employ the removable plug 6. When this is removed a- 7 string or flexible brush can berun in and through the tube to clean it out.

I have found that liquid can be admitted through an aperture 7 in a plug 6,

to facilitate the, action of escaping air m and from the trunk.

' When desired, the trunk may be oflarger diameter than the tube neck, as is shown at 2, Fig. 4. This aifords a large volume of air in the trunk ocket to effect a dischargeof liquid and in ucing a flow.

What is claimed is:

1. A self-starting siphon device comprising communicating portions; the latter orming an elongated, closed bottom air. chamber submersible in liquid, the passage from the chamber to the goose-neck being free and unobstructed for oose-neck and trunkstructed passage. r I 2. A siphon device having a one-piece tubev trunkthe upfiow of air, and the trunk being laterally apertured, in its u per. portion, for the free inflow of liqui having a goose-neckand a closed bottom part having a straight, direct, -unobstructe and unrestricted ine of com'municationwith the goose-neck; said trunk-hav- I W ing an 0 min at its upper part for the infiow of iqui when the trunk end is submerged.

3. A siphoning device comprising a tube of generally uniform diameter having a goose-neck with a trunk part, closed. at its, submersiblebottom end; said tube having a into the unobgoose-neck; sa'l liquid, inflow mouth-in the upper portion of the trunk.

4. Asiphoning device comprising a tube having a trunk part, a removable closure Ior the bottom end of said part, and a gooseneck for the upper end of the trunk; the' passageway into the trunk.

closure having a small 3 RENSSELAER TOLL.
